Here is how I installed my front rotors from EBC (MD616) on my '09.
EBC doesn't offer bushings/standoffs that I can find. I used Wunderlich fittings offered for their Lucas rotors.

, you'll need two sets.
Here's my story: The factory rotors weren't worn out, but the dealer failed them on state inspection because they had side-to-side play (barely noticeable). The reason is that the springs that hold the rivets in place get weak, and bolt torquing is not a substitute. I have attached a PDF of my repair, with pertinent photos.
